Free accounts cap at 100 MB per file, and DivX sources run large because the format carries substantial per-chunk overhead on top of the video data. Premium raises the cap considerably. If the file is split into numbered parts because of the format ceiling, upload them together and they are treated as one job.

Frame extraction is fast — typically 20 to 30% of source duration on the standard pipeline. A 5-minute DivX → TIFF bundle finishes in about a minute regardless of frame count, because the bottleneck is the TIFF encoder, not the DivX demuxer.
