Re: [CinCV] Cannot solve this problem
Did you tried to fix the window to the picture with the right clic on the time line ? Sometimes window is not calibrated to the image .. haldun Le 21/11/2012 13:12, Basil Chupin a écrit : I am unable to solve this problem I am having in converting an mpg file to avi as input into Cinelerra for editing. Can anyone, please, give me a clue on how to solve it? The .mpg file, which is 10.4GB big and is a program recorded off the TV (digital, terrestial) has these details: Input #0, mpeg, from 'Flying_Machines.mpg': Duration: 02:45:23.62, start: 13078.001922, bitrate: 9217 kb/s Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p, 1440x1080 [SAR 4:3 DAR 16:9], 15500 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc Stream #0:1[0x80]: Audio: ac3, 48000 Hz, stereo, s16, 448 kb/s I have been using this CLI 'script' to convert my mpg files to avi (and I can work on them successfully in Cinelerra): mencoder -vf harddup -demuxer lavf -oac pcm -ovc lavc -lavcopts vcodec=mjpeg:vhq:vbitrate=6000:autoaspect=1 -noskip -mc 0 -ofps 25 -o output.avi input.mpg However, when I put the ABOVE file, after it has been converted to avi by mencoder, into Cinelerra, the resulting edited file which appears in the COMPOSITOR window is a zoomed version of the original- ie, I lose part of the picture on all 4 sides. BUT, the TIMELINE shows each frame as it should look - ie, there is no loss of picture and all the details is therefore there as in the original recording. I then used WINff which I found here: http://www.g-raffa.eu/Cinelerra/HOWTO/get_media_ready.html and applied the 'Grandma's Fix', Using the Graphical User Interface - WinFF, and then followed the instructions given there to convert the mpg file - ie, used Cinelerra intermediate formats and Select DNxHD as Preset. When I do that I get the following error message: I tried a number of combinations of bitrates etc for both video and audio but get the same error message. Can anyone help please re this problem? I may not have provided sufficient info as I don't know what is most relevant. BC ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

Just to give you, et al, an idea of what I talking about here is what the original film looks like: http://susepaste.org/38587013 Here is what it shows in the Viewer and the Compositor windows in Cinelerra: http://susepaste.org/82285960 and here is what the frames on the Timeline look: http://susepaste.org/18058509 BC -- Using openSUSE 12.2 x86_64 KDE 4.9.3 kernel 3.6.6-1 on a system with- AMD FX 8-core 3.6/4.2GHz processor 16GB PC14900/1866MHz Quad Channel Corsair Vengeance RAM Gigabyte AMD3+ m/board; Gigabyte nVidia GTX550Ti 1GB DDR5 GPU ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

BUT, the TIMELINE shows each frame as it should look - ie, there is no loss of picture and all the details is therefore there as in the original recording. I'm pretty sure it's because the track canvas size is smaller than the video's and the project's resolution. Old annoyance, that has bitten me time and again. Do as Haldun suggested, right-click on the video track, and pick the to project size item. That should do the trick. Aside: Sometimes, smaller sized tracks ARE useful. But Cinelerra's behaviour does not quite fit the user model, obviously. Thanks for the response, Herman. I tried what Haldun suggested - without success. What has me a puzzled is the 4:3 format followed by the 16:9 format in the mpg file details (shown in the first post of mine). The original film has a sort of 4:3 formaty look when it starts which then changes into something like 2.20:1 format after a few minutes and then the format changes to 16:9. So there appears to be 3 formats within several minutes of the film (at the beginning).

It only accepts two resolutions: 1280x720 and 1920x1080, and only combined with a fixed set of framerates and bitrates. Beware!
