VLC rapidly changes color when playing AVI clips

Postby avz10 » 13 Dec 2013 20:19

I captured nearly 60 VHS cassettes with VirtualDub using a S-VHS JVC HR-S8960 video recorder which has a Time Base Corrector with Digital Noise Reduction, but captured "normal" VHS cassettes. I did some basic cutting in VirtualDub and eventually had approximately 300 clips! (There were a lot of duplications, as I made a separate series per child). I used the Lagarith codec to compress. This was whole part was hours and hours of work. I have grouped them in separate groups and want now with different AviSynth scripts to improve the quality as much as I can. (This was my second attempt-I made an error of some sort a previous time and the quality was very bad.)

Unfortunately, I did not check the audio-video sync and they are out in quite a large number of clips. After researching, asking, etc; I found that the easiest way to solve the sync issue is to play a clip in VLC and with the shortcut "J" or "K" to find the difference. The value that I got, I would then load in VD and saved. I corrected quite a few clips, eventually encoded them with TMPG and played on TV. The results were quite good.

I am currently working on my laptop as we are moving and I am in a different part of the country. I therefore do not have my best equpment, but still ufficient. Space is a problem. All the clips are stored on a 1 TB external drive. When I practiced, I copied some clips on to the hard drive of the laptop, played on VLC and then saved also on the laptop, then sent the corrected clip to the hard drive. No problems.

My laptop:

Code: Select all

Fujitsu Lifebook s760 Windows 7 Professional (x64) Service Pack 1 (build 7601) 2.13 gigahertz Intel Core i3 M 330 Multi-core (2 total) Hyper-threaded (4 total) 3892 Megabytes Usable Installed Memory
Last night I started in all earnest. I deleted my current copy of VLC and installed version 2.1.1 (x64). Playing a video, made the colors change every few milliseconds. I changed to 2.1.2 (x32), then also changed to some of the older versions who did not want to play the clip due to the Lagarith codec. I tried a number of clips. All made the same error. Unfortunately, I do not remember what previous version of VLC I was using.

I use this clip as an example:

Code: Select all

General Complete name : C:\Users\User\Videos\1a. Projek Des 2012\1986\troue 1.avi Format : AVI Format/Info : Audio Video Interleave Format profile : OpenDML File size : 2.14 GiB Duration : 5mn 54s Overall bit rate : 51.9 Mbps Writing library : VirtualDub build 32842/release Video ID : 0 Format : Lagarith Codec ID : LAGS Duration : 5mn 54s Bit rate : 50.4 Mbps Width : 720 pixels Height : 576 pixels Display aspect ratio : 5:4 Frame rate : 25.000 fps Standard : PAL Color space : YUV Chroma subsampling : 4:2:2 Bit depth : 8 bits Bits/(Pixel*Frame) : 4.861 Stream size : 2.08 GiB (97%) Audio ID : 1 Format : PCM Format settings, Endianness : Little Format settings, Sign : Signed Codec ID : 1 Duration : 5mn 54s Bit rate mode : Constant Bit rate : 1 536 Kbps Channel(s) : 2 channels Sampling rate : 48.0 KHz Bit depth : 16 bits Stream size : 64.9 MiB (3%) Alignment : Aligned on interleaves Interleave, duration : 40 ms (1.00 video frame) Interleave, preload duration : 500 ms
Examples:

I do not want to change over to RGB at this stage and I suppose the problem lies with the color space. Is there another color space that I need to change to before I can play it in VLC? I do not think MPC has this easy shortcut ability.

Is there anyone that can help?

You have the issue only in Lagarith videos?
