H.264: Incorrect frame rate could be picked up if there are 3 or more GOP headers before first frame slice. Program stream output: Fix edge case where a packet of nulls could have the PTS for the next real frame. MPEG1: Added support of common aspect ratio codes (4x3 and 16x9) for MPEG-1 codec. Audio normalization: Automatic normalization algorithm might not normalize up to the last 400 msec of the file.

H.264 encoding: Media Info incorrectly reports non-constant frame rate for files transcoded to H264 MP4 due to DTS adjustment. GUI: Crash if T>O>Playback, YUV acceleration un-checked and frame dimensions change during playback.

GUI: (VRDPro) Remove requirement for additional license to support H.264 4:2:2 & 10 bit. MXF: (VRDPro) SMPTE-436m captions might not display if there are multiple ANC packets and 436M packet has stuffing bytes at end.
TVSuite V5 - 5.3.83.766a (Released ) = Transport stream mux: Reduce number of PTS overflow/underflow messages that go to the log to cut down on log file size. Uncompressed: Changed video buffer overflow size test from >= max_buffer_size to > max_buffer_size. Programs that should be displayed in a widescreen format are "letterboxed" with dark blank areas above and below the programs.Īuto-cropping of letterbox material will remove the blank areas above and below the program material and create a true 16x9 (anamorphic) DVD or video.TS Muxing: Not writing a language descriptor to the PMT when audio is AAC-LC. However, programs captured from some sources such as a video capture card or DVD recorder will store the video in 4x3 format. Depending upon your source material, GOP boundaries occur every 1/2 to 30 seconds.įor optimal playback, especially on wide screen monitors and devices, the video should be stored in its native aspect ratio of either 16x9 or 4x3. A GOP boundary is where the original encoder has encoded a complete frame. Without VideoReDo's special capabilities, the only place you can cut safely is on a GOP boundary. You will either remove wanted program material, or leave in parts you did not want.įrames in a compressed video are not stored sequentially and most frames are stored simply as changes from some prior frame. No matter what the original source.īecause if you don't have frame accurate editing, you will not be able to specify the exact cut points resulting in a very chopped looking edit. VideoReDo automatically processes files so that when these tags are removed the resulting audio and video streams stay in sync.

When a program is authored to DVD, these time code tags are removed by the authoring tool and potential sync corrections are lost. When you capture your video, your audio and video information contains time code tags which keep the playback in sync.
Transferring from tapes has its own unique set of sync problems as the timing of consumer VHS players and old, noisy tapes can quickly result in out of sync DVDs. For example, if you are capturing off the air, cable or satellite, a transmission error can result in dropped video frames. Why do my videos get out of sync when saving edited videos? With VideoReDo's perfected smart rendering technology you can edit again and again without degrading any of your precious videos. More importantly, each recoding results in a reduction of quality. The result is that it can take hours to save your video rather than just minutes as it does with VideoReDo. Most full-featured video editors convert your videos into uncompressed video for editing and then re-encode it when saving the edits. HEVC, H.264 and MPEG are highly compressed formats.
