Blaupunkt RTV-950 TBC On or OFF while capturing through a Sony miniDV?

Hello,
I know this must have been answered somewhere, but sorry I can't find it. So I am capturing VHS tapes from Blaupunkt RTV-950 (clone of Panasonic FS200) through a Sony TRV33 miniDV as a passthrough. The signal goes straight from miniDV by Firewire to PC to WinDV.
It is not stated in the specs but most here agree that this Sony does have a good TBC which can't be turned on or off. The Blaupunkt does have a Line TBC. So shall I have it On and thus have 2 TBCs involved in capturing or Off? I know that I should test this by myself. For me it seems that I should turn it OFF. But I may not been so keen and don't have so good vision. So maybe there are folks who have allready tested this many times and can tell their opinion?

Thanks!

Differing Frame Rates

So I have some 1080p 60fps video from our camcorder. It's all OK. But I also have some from my Nexus 6p phone, which is 1080p 30fps. I'd like to use it with the 60fps video. Is there something I can do to combine them? I've never used multiple frame rates before in Vegas, or any other NLE
Thx

The capabilities of Blaupunkt RTV-950

Hello all,

I am now in a process of evaluating the image quality and the capability of DOC (Dropout Compensation) of my Blaupunkt RTV-950 (clone of Panasonic FS200). I bought it from Ebay.de with a fault but in mint condition. It was repaired by a highly skilled master who was himself a constructor of VCRs in the 70-ies! So I would assume that it should be in a near perfect condition now. But sadly it is not. When compared to my other non S-VHS machines which are HiFi VCRs I see 2 major flaws:
1. it is less capable of correcting dropouts in a number of VHS tapes. I find specific places on these tapes with more and less severe dropouts.
2. the image quality seems to be worse too. I know that it is sometimes easy to confuse the image detail with the noise. But for me it seems worse. I see what I would call shadows or ghosting of lines. The TBC and Noise Filter does it's job well, but that does not help if the image is read worse in the first place. Most of the time I compare the image with TBC and NF Off to have a fair comparison. But even in On position my HiFi machines win. The LG LV 880 must be one of the last generation VCRs. Can this be the reason? I guess no. As I have read in many forums Panasonic FS200 has been judged as a reference machine.
So I have no other idea as that my Blaupunkt is not at it's best. My only explanation is the one I like the least- my highly skilled specialist has repaired the electronics faults, but has not been able or has not had the chance to check if the machine performs at it's best in real life.
What would you say about the comparison of highly evaluated S-VHS and new era HiFi VCRs?

Hardcode subs into mutiple mp4 file at once?!

I have search for a while now and didn't find anything similar or maybe I didn't searched enough but I want to hardcode over 12k of mp4 files , so I wonder what is the most easy way to do it ? Is there a program or a script that can detect the mp4 file and subtitle file and hardcode multiple video files ? Like a batch script or something. But also with the possibility to set the font size and style. Even if it's a software that you now , I will buy it if it's doing the job.

Thanks,

Two-Pass Encoding using AVS2YUV with FFmpeg

March 9, 2017, 11:29 am

I am trying to pipe AVS scripts to the 64 bit version of FFmpeg for x264 encoding using avs2yuv. My problem is 2 pass encoding. Without piping, it works fine. Here's an example of the code I'm using.

Code:
ffmpeg  -y  -i <inAVS>  -c:v libx264  -b:v 6000k  -pass 1 -preset medium -an  -f mp4 NUL &&\
ffmpeg -i <inAVS>  -itsoffset 0.045 -i <inTempWav> -map 0:0 -map 1:0  -c:v libx264  -b:v 6000k  -pass 2 -preset medium -c:a aac -b:a 256k  <outFile>.mp4
For single pass encoding using avs2yuv, no problem. Here's an example.

Code:
avs2yuv <inAVS> - | ffmpeg -y -f yuv4mpegpipe -i -  -c:v libx264  -crf 23 -preset medium -an  <outFile>.mp4
However, for two pass encoding, I cannot get it to work. Here's the code I'm using.

Code:
avs2yuv <inAVS> - | ffmpeg -y -f yuv4mpegpipe -i -  -c:v libx264  -b:v 6000k  -pass 1 -preset medium -an  -f mp4 NUL &&\
avs2yuv <inAVS> - | ffmpeg -f yuv4mpegpipe -i -  -c:v libx264  -b:v 6000k  -pass 2 -preset medium -an  <outFile>.mp4
In the log file I get this error message--Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

I suspect the problem has to do with how the log file is being set up during pass 1. Any help would be appreciated. Thanks.

FFMPEG and out of sync avi

I have OTA recordings (WTV--> MPG) which are then converted to avi that are out of sync (DGIndex confirms that the mpg audio has a positive delay).
VLC and MPC bring it into sync using a positive value of 250.
There is a method of syncing using a command line in ffmpeg that seems to work when the delay is negative.

http://alien.slackbook.org/blog/fixing-audio-sync-with-ffmpeg/

Quote:
ffmpeg -i bbt.avi -itsoffset 0.25 -i bbt.avi -map 0:v -map 1:a -vcodec copy -acodec copy insync.avi
It doesn't seem to work for positive delays.
Any ideas?

remux mp4 question: PLEASE HELP

I have an mp4 with subtitles and audio that I want to remove, just keeping the video and the ac3 6 channel English audio. I also want to add a 2 channel AAC audio to the mp4 so I can play on devices that can't decode ac3. The way I was doing it in the past was to:

1.) Open the MP4 with MKVToolnix and remove the files I don't want and save as MKV.
2.) Load the new MKV into Vidcoder and add a second audio, creating the 2 channel AAC file back into an MP4

I know this is not the best way to achieve this so can someone please advise if there is a way to achieve the above without quality loss/re-encoding?

Thanks for your help in advance.

Problems with playing 4k x265 files

Hello,

When I play a mkv x265 file on VLC, it stutters, freezes and sometimes crashes. It won't work
It also uses a lot CPU.
When I play it with windows media player or movies and series, it works just fine, it uses like nothing of my CPU ( 7/8% ) or memory, but with some files it won't play sound, only video. Is there maybe a solution for?
I also downloaded an other media player Potplayer, it works fine, but it uses all my memory and CPU.

Info about my machine:
OS: Windows 10 Pro 64 bit
CPU: i5-7600 3.5 Ghz
Memory: Corsair Vengeance LPX 16GB 3000MHz DDR4
GPU: Nvidia GeForce GTX 1070 (8GB)
HD: Seagate Barracuda 1 TB

Questions are, why doesn't VLC player works with 4k files and all the other programs do, 2nd why does VLC and Podplayer uses so much cpu and memory when windows media player and movies and series doesn't do that, 3rd Why does some files doesn't play sound on windows media player.

Thanks for your time.

Regards,

Teague

How to download streaming videos (not too simple)

I have a site that contains some web streaming videos in which they are SO difficult to download. At least I've tried most of the Google extensions and Firefox addon, VSO downloader, and many similar programs in which none of them could download anything. They downloaded very small files like 1-2 kb which are empty.

Is there any very powerful tool that could download almost any streaming videos no matter how they put it on the web?

Any recommendations?

Not using a laptop (mean not turning ON ) for quite some time (let say half a year), could the hardware inside get rusted more easily ?? Because I guess hardware components are usually made of metals

Another question about desktop PC.

I have a desktop PC that I would clean out the dust from time to time (usually 2-3 months a time), however, I never use any moist cloth to wipe any hardware directly. I always only use dry brush and that's it. Is it OK? Anything more I have to do to keep the PC the best

I wonder can I re-encode a MP4 changing the colormatrix fron 601 to 709 in vcodec copy? No? however is there a way to tell to ffmpeg that, in case of transcoding, that it have to change only the colormatrix and preserve all the video part as is?

thanks

AviDemux - [ and ] Set Marker A/B no longer works

So in an earlier version of A/d I could use [ and ] as A and B

In the latest it no longer works and I am forced to using some ridiculous setting of Ctrl+PgUp and Ctrl+PdDn

Even though their own site says something totally different, and get this, all google sites come up with different ways

Are they changing the settings for this superb editor with each version

Is there a way I can set it back to [ and ] (which is intuitive really speeds up my editing) without going back to the old version ?

I like the new version as it shows us key frame locations and doesn't reposition upon zoom which was very unnerving.

Thanks in advance !
