Hi OTW,
Following your suggested test to the letter, I did a few experiments. Here, for what they're worth, are the results.
Test #1
- Placed 720p (01:29) WMV sample clip in timeline. Clip aquired online
(

- Followed OTW instructions > copied second split to end of video
- Applied Reverse Video effect
Preview playback stuttered a little when the reversed snippet was reached, but then played on normally.
- Produced to WMV9 HD Standard Quality.
Playback in WMP and VLC players was flawless.
Test #2
- Placed 1920x1080 AVCHD H.264 MTS sample clip in timeline.
(Clip was acquired here on the forum from member)
- Followed OTW instructions > copied split to end of video
- Applied Reverse Video effect
Preview playback had major stutters and became almost a total freeze when the reversed snippet was reached.
- Produced to WMV9 HD Standard Quality. (tried others as well)
Production/ rendering appeared normal, with SVRT on or off. However, upon reaching the reversed section, I got a popup saying “out of memory”. (I had never seen that popup before)
Playback in WMP and VLC players? Unable to Produce, so no playback results.
Test #3
Same as #2. Only difference was that tested clip was PAL, and at a higher fps rate. But results were identical.
Conclusions
Working with the 720p clips, and having one play in reverse, did cause some stuttering in the preview set at High Resolution, though once Produced resulted in a flawless production and playback. Making the Reverse Video effect a completely viable option to use in my productions.
However, stepping up to full HD (1920x1080), the reverse effect would not work for me. But I attribute that more to me using a computer who’s specs are not up to the task of effortlessly dealing with full HD, and not necessarily the Reverse Video effect itself.
