Anyway to restore all frames from NTSC>PAL animation

March 5, 2017, 6:29 am

Hi all

Wherever possible (assuming there is no Blu-Ray available) I will buy NTSC sourced DVDs for animated series as more often than not they can be detelecined to provide a decent 480p video. However sometimes there is no option other than to buy them from UK which means they are 576i50. Now inlike films, animated series don't tend to have PAL speedup, instead relying on a crude frame conversion. Deinterlacing these clips even to 50fps still leaves some juddery ghost frames.

I'm guessing it's impossible to get back to the native 23.976fps but what is the best way to get closest to this? I've played around with virtualdub quite a bit but never made the jump to avisynth.

Interested to read people's thoughts!

1280x694 video gets blurred after resizing 720p with\without letter box

Hello guys,
I have a video which is 1280x694 I try to resize it to proper 720p, I am adding black bars to keep video aspect ratio and avoid blur, but for some reason video gets blurred. Encoding without size change keeps video quality intact. I tried h264 and x264 and lagarith loseless. Used vegas pro, virtual dub and handbrake.
Here is sample video https://www.sendspace.com/file/abqxej - it is h264 in avi container to make it accessible from virtual dub. Try yourself.
Is there some command line to fix that issue?:confused:

Performance problems with 4K H.264 playback on NVIDIA GTX 770

Hi,

I've recently purchased a 4K capable camcorder (Panasonic HC-X1). But I have serious trouble playing the recorded 4K files (2160p50 @ 150 Mbps). The playback stutters in intervals of a few seconds, sometimes it shows ugly block artifacts.

The problem occurs:
  • on Windows 10 (all updates installed)
  • with NVIDIA GTX 770 graphics card (driver version 378.66)
  • monitor resolution is 2560x1440 @ 60 Hz
  • all players are affected (Movies & TV, Windows Media Player, MediaPlayer Classic, VLC)

As far as I can see the video hardware acceleration is already fully enabled, since the CPU load stays well below 10% at all times (i7-4770K).

The problem does not occur when:
  • using VLC on my desktop computer (with NVIDIA GTX 770) but using Linux instead of Windows
  • using some other computer (laptop) without dedicated graphics card (Intel iGPU, also Windows 10, Movies & TV or Media Player)

How can I fix the playback problems on my desktop computer with Windows 10?
Are there any diagnosis tools to debug the problem?
I'm using my Windows desktop for all video editing, hence a proper clip preview is crucial for me.

Yours,
Daniel

Problem Copying VOB from Homemade DVD

I have successfully ripped all other VOBs from 4 DVDs and edited into 1 MP4 file. It's a sporting game. The last VOB on disc 4 is highlights of the game. It is very stubborn to copy cleanly; rips real fast but the file always stutters and shows its runtime at 2 plus minutes (it's 11 minutes). The disc is scratch free. Can copy the other files no problems?

edit to add it plays smoothly in set top player and on the computer just fine.

How to Create Such Subtitles on Videos?

Hi, dear all.


Do you know how to create such subtitle like the picture below?



Attachment 40844 (click for full size)


I want to create subtitles similar on the picture: one black bar ( like a kind of background or frame behind the subtitle ) that "contrast" with the subtitle itself.


Its that possible to do it?


In such cases, which program can do that ( freeware if its possible or available )?


And in such cases the subtitle must be hard-coded ( embedded ) on the video or I can do it "soft coded", like a simple SRT or ASS / SSA subtitle formats?


Thanks for the tips.


Best regards.

Exporting A Video with Several Audio Formats

March 5, 2017, 3:02 pm

Hello,

I have a Premiere Pro CS6 sequence with audio and video from a VHS tape. The video (and scratch audio) was originally recorded onto DVD at 9,100 Kbps using a Panasonic DVD recorder, connected to a separate VCR for the tape's playback. I used another program to passively import the disc's VIDEO_TS files into one .mpeg file, which was then imported into Premiere. The audio was captured simultaneously from the VCR at 32-bit (float)/48kHz using Audition CS6, where a copy was edited (eq, multiband comp), and saved as a 24-bit/48kHz file. I imported that file into Premiere and aligned it with the scratch audio from the DVD.

The video looks great, needing only a slight black/white levels adjustment, and a narrow crop at the bottom, so keeping it high quality is a must. The big question is about exporting the same video with several different audio formats. Should I leave the 24-bit/48kHz file in the timeline, and let Premiere (or Media Encoder) convert it to ac3, AAC, and 16-bit, uncompressed LPCM files on export? Conversely, should I use Audition to take the 24-bit/48kHz file and "Save As" each of the aforementioned formats, which would then be imported back into Premiere sequences? Would it be more efficient for Premiere to export the H.264 (AAC), and MPEG2 (ac3, WAV) video files with their corresponding audio already encoded at the correct spec beforehand, or does it even make a difference? Should I export using Media Encoder instead? The audio is live music from some shows I played some time ago. It sounded good raw, and now really sounds good after the appropriate editing, so keeping keeping the audio at the highest quality level is paramount. I'm not experienced enough in video editing where the audio is a super-critical, analog tape music source, so I don't know which direction to take. I do know that the video is destined for DVD, and for online viewing. In a nutshell, should I perform all of the audio encoding first in the audio software (Audition), or simply let Premiere/Media Encoder do the audio encoding during export?

I appreciate all comments and suggestions. Thank you.

Hello.
I have project in vegas, I frameserve them to virtualdub into x264 codec which saves just video in mp4 file. Then I run vegas again and just saving audio, mp3 or ac3 or wav. I tried to mux video and audio with tsmuxer and mymp4box - video and audio have exact same duration but for some reason audio is delayed about 0.5-1 second.
What am I doing wrong?

Remux vs Encodes?

Hi guys,

Few quick questions about this:

1. Remuxes are 1920x1080p and 1080p encodes are actually 1920x800p, though they both have the black bars. Is there a loss in pixel density in encodes compared to remux? Both look the same.
2. If I download a DTS-HD encode, is the audio quality still compressed (My understanding is that it's not)
3. Is the difference in quality really worth it?

Thanks

Improved Browser Color Rendition

March 6, 2017, 5:55 am

I don't know what's changed, but the color rendition on Mozilla Firefox, Chrome and Opera has improved greatly on both local files and YouTube videos.

These browsers used to have grievous color errors on both local and streaming videos. VLC, Windows Media Player and Microsoft Edge still have serious color errors -- not so with the three browsers. mentioned.

I am surprised that the videos still look good on YouTube, considering all of the resampling they do. The errors are down to +/- 2, within rounding error for floating-point calculations. For example, my test pattern contains a yellow patch consisting of R = 180, G = 180, B = 16. The three browsers mentioned give R = 178, G = 180, B = 15, not perfect but a great improvement over, say, a year and a half ago. I am using Windows 10 but I'm inclined to think the improvement is not due to the change from Windows 7 to Windows 10, or we would be seeing improved color rendition on VLC, Edge and Windows Media Player. That we get different results on different video players suggests that the errors are on the decoder side rather than the encoder side.

Here is a link to the test pattern I used. The colors can be checked with any "eyedropper" color checker.

OCR a video with Google's OCR

March 6, 2017, 8:38 am

Hi,
It’s a while now that i’m wondering how could I OCR a full video.
I know that there are programs like SubRip and AviSubDetector, but they aren’t the best, they struggle with complicated fonts, they need a lot of manual inputs and they are a bit clucky in general for what I need them to do (OCR hardsubbed cartoons/anime episodes with complicated fonts), they aren’t practical enough.

So I’m thinking: is there a way to use google keep’s ocr to do this? It’s the best ocr i know at the moment and it recognised everything i threw at it, but it only accepts images that aren’t larger than 4Mb.

I just discovered AutoIt, so i’m wandering, is there a way to automate the process of: converting a video in a jpg sequence, crop every image, upload the first on Google keep, do the ocr, copy the result, paste it somewhere, delete the image and upload the next one?

Obviously I didn’t take in consideration the whole “timing” question, so i’m creating a text file with only the actual dialogs, without time stamps.
But maybe it can be done, utilizing AviSubDetector: when it stops because it recognised a subtitle, i grab the timing from it with the autoit script and i paste it on my text file.

These are just ideas, but i’d like to know what you guys think.
Is there a better way to ocr an entire video with a google ocr engine? (not tesseract, as far as i know it’s not even near google keep performance-wise).
Or maybe a better one, if it exist.
Let me know :)

File Size Issues

Hi everyone,

I am recording VHS videos (some as long as 4 hours) with a Diamond VC500 using AmaRecTV and the HUFFYuv codec. My laptop that I use for this has a 256 GB SSD with normally around 100 GB of free space. With some of these tapes getting near 4 hours, I am having trouble with filling up my entire hard drive with one tape. I then offload it to a 3 TB External Seagate so that I may move onto the next VHS. These offloads can take anywhere from 45 minutes to an hour and a half depending on how well the Seagate External Hard Drive wants to act. If I try to record directly to the Seagate, the video recording with freeze and eventually fail. This is getting a bit ridiculous for me and I would like suggestions. I have been looking into recording directly to an external SSD, but would like to see if anyone else has this sort of issue.

I am also wondering about any suggestions that people could make to make my setup better. I just started recording VHS' just a couple months ago for family presents and have really gotten into it.

Problem with recording electric guitar (distortion problems)

March 6, 2017, 12:24 pm

I want to upload a video tutorial on how to play a tune on the electric guitar. My problem is: when I play the recorded wav file, on certain devices (my mobile phone and one of my laptops) the sound is distorting. I noticed that on the same problematic devices, when I play the tutorials of others from Youtube, the distortion also occurs, so it has to be a problem of the properties of the speaker of these devices (the original audio tracks released by bands doesn't distort though). I wonder if I could improve the sound so less distortion would occur?

Find a sample from my recording attached to this post.

Here are some details about how I recorded this:
- For this sample I recorded the guitar with delays and EQ added before the input. However, the distortions also occur when I record in a way that the guitar is plugged right into the input, maybe a little lesser though. (I set the EQ in a way to emphasize high frequencies, maybe that raises the possibility of distortions?)
- The recorded signal never had clipping. Actually what you can see in the sample is the signal I recorded, the only editing I did was doubling the channels, because originally it was mono.

So the playback is okay on my desktop speakers, on my iPad and HP 625 laptop, but it is distorting on my mobile phone and my HP Probook. If you have any ideas how I could make the signal a bit more consumable for the last two devices, I would appreciate.
