Animation: rendering to single frames (many),joining them efficiently and compressing in good quality(to little ram to load all)
show user profile  Tomasz79
Hi. I`m rendering camera flythrogh type of animation in 3ds Max and V-Ray. It is 1800 frames, one minute and I render each frame to single file, png files, 640x480. I cannot render it to avi in one single take, since I have to use the computer for something else meanwhile, and stop the rendering from time to time.

If it was shorter, I would load it all in RAM Player, all the frames and used Save As afterwards, choosen AVI and compression type. However, it is too much for my RAM (2Gb, under Win XP) and those frames can not load all together. I would appreaciate any help, as to how to do it simply, any recommended free programs that can join single image files into movie files, or perhaps I could load in Ram Pl. half (900) frames and save it as uncompressed file, load second half, save as part 2 and in another program join thosae big uncompressed avis into one, compressed one?

Another thing is, I don`t want to loose any more quality than nessesery in this joining and compressing process, and that is also the reason why I ask, since perhaps someone understands it all better and can give me a hint. In Ram player, there are not much comp[ression options, like cinepak radius, or indeo video, and oin both situations when I test it on smaller frame counts, results (compressed avis) are not great, anyone got any good ways of compressing avis / mpgs or movs? Thanks for your time.

Max can easily do this. Use the Video post option. Add an image input event, choose the first frame, tick "sequence". Add an output event, choose avi, choose the output settings. Hit the little running man, and you are done.

Yeah, VirtualDub Mod will do the trick for you. I promt you to VD MOD not VirtualDub, because with MOD you can have M-peg4 compression.
Let me know how it goes.

Oh, almost forgot, to attach your frames together just select File->Open Video File->and select the first frame, they will all come together automatically.
If you find that the animation changed speed, or is not syncing properly to the audio just go to Video->Frame Rate->and select 'Change to' and input the number of frames per second that your animation is. I dunno why but sometimes VDub screw this up, so you have to 'force' it in place with this procedure.

Another Edit:
You have to got to Video->Compression... To select what Codec you need and be sure that under the 'Video' menu you select 'Full Processing' mode to apply the compression!

Virtual Dub is good, but you really don't need it, as max does it.

And, it will save the Video Post settings with the max scene, so to re-export it as a compressed AVI, the setup will stay with the file.
