AVC vs. MPEG-2 Renders (Revisited)
Despite what I do, I cannot get AVC (Blu-ray template) renders to play back in ANY program I have on my PC if my production is an hour or longer (maybe less, but I only have tried less than 2 minutes or more than an hour). I am using SVP 12 and DVD Architect 6. My latest 1 hr. 18 min production(shot in 1920X1080, 60i) renders fine using MainConcept MPEG-2 25Mbps to create an m2v file, and I render an AC-3 file seamlessly from the same veg file. If I attempt an AVC render (either Sony or MainConcept at 16Mbps), the file renders but I am unable to play it back. Curiously, too, in Windows Explorer the m2v indicates the length of the program, but this item is not showing for the AVC (or AC-3) files. With respect to render times for my 1:18 Bar Mitzvah ceremony , Sony AVC (16Mbps)took 2:30, MainConcept AVC (16Mbps) took a whopping 4:30 (rendering a few seconds at a time, then stopping, only to repeat this over the 4+ hours), and MainConcept MPEG-2 (25Mbps) came in at 1:09 (less than real-time). All were completed with my GPU ON. As a control, I just rendered the 1.5 minute open to this Bar Mitzvah video to Sony AVC at 16Mbps with success, It opens and plays fine in DVD Architect!! So it appears that I am stuck with MainConcept MPEG-2 for longer productions, which works just fine and the video and audio are crisp as can be!! I just am curious if I am the only one experiencing this anomaly with unsuccessful (and way too long) AVC renders for programs of at least an hour in length. Has ANYONE gotten a successful AVC render for a 1 hour or longer program? Is it true, then, that this is a known bug in SVP 12 (per the Release Notes stating that “You may not be able to render files larger than 4 GB using some combinations of settings in the Sony AVC encoder”)? If so, exactly what combinations are these and what WILL work properly? Does the rendered bitrate make that much a difference or could this be causing a problem? Is it even worth my time at this point to keep seeking answers to these incompatibilities and just use what I does know works, and works fast? Thank goodness SVP 12 now is somewhat stable (after all of the tweaks suggested on this Forum), and I even can use my GPU for editing/rendering, to boot!! This is a victory of sorts!! Any ideas/similar experiences, then, on this AVC rendering issue?
