Slower fps rate on Pal capture
1 Attachment(s)
Hi all.
Got my first TBC/DNR JVC machine and want to transfer back all the 100 tapes I have. Last time I did it was 10 years ago with Windows XP machine and a standard 2 head VCR, with some EZcap app or Ulead for capturing. I saved the files as MPEG2 DVD with around 7000bitrate at that time. Now I capture Lossless with Vdub (avi) and the video is looking good but slower than my MPEG2 files. I have attached a screenshot of the FPS counter on VLC. The new capture (left) is counting 25FPS while the old MPEG2 (right) is counting 50FPS. Both of the Frame rates are 25 as you can see in the Codec information. What could be the reason the lossless file looks slower to my eyes? I think it's something with the interlace as I have an option on VLC to turn deinterlace off- the old file goes to 25. But the new capture stays 25 while it's on or off. |
Sounds like your new system is deinterlacing and recording as progressive scan.
Technically analog PAL is 50 Fields (field = half the lines of a frame where you get only the even numbered or only the odd numbered lines) second and 50 frames (a frame being 2 fields combined) a second. Some people can tell the difference (especially on sports or fast motion content) between interlaced and progressive scan video. |
Got it sorted with hybrid after processing the file with de-interlace QTGMC
