Digital Workshop

I have two videos playing simultaneously, the one without subs "on top" and the one with subs "on khroma key" and the "sound mute" so both sounds don’t overlap.
Is there any way of creating actions in a button, so I can "hide" the video on top, an I would see the one with subs but with de sound of the one on top, and "show" again the one on top if I don’t want the subtitles?
The normal options "hide" and "show" don’t work for that, they just stop the video (and the sound on it).
Thanks

Set both to rendered and then use the set layer function to switch between the two.

BTW - add your OPUS version to your profile.

Trying to run two (2) videos at the same time is a recipe for a disaster. Unless these are very short (small) videos, and you are always sure your viewers have powerful computers plus they will be watching from a hard drive (not a CD-ROM), (videos use the most resources - RAM & processing), you are running the risk of being out of sync, stuttering, or just won't play. If you have been testing on your computer's hard drive, and the final product will run from a CD-ROM, you should Publish and test in that environment. Even then, some CD-ROM drives run better than others. Notebook computers usually have their CD-ROMs idle after an initial load to conserve battery life. This will mean a long pause while the CD-ROM drive spins back up to full speed to read two videos. I'm speaking from experience. Learn from my mistakes!

Solution:
I recommend you have the viewer make an initial decision to either watch 1) the video with sub titles, or 2) the video without sub titles. Only one video will have to run then.

Fred's right - it's a numbers game.

I ran the following:

Two identical 20mins segments extracted from a DVD - one with subs, one without. These were transcoded to MPEG1 at 720x576 at 1700kbps using Mainconcept's codec. Both were added as rendered video to Opus, with the sub-titled version overlaying the other and its audio muted. Two simple play commands were used to run the videos together. The file was published with the videos not embedded.

The test machine was a five year old laptop - Pentium M 1.8Ghz with 1GB of RAM with a 5400rpm hard-drive.

The sound remained in sync for the whole 20 mins and the playback / quality was acceptable for a basic publication.

As the designer, you aim for a publication that operates within the limitations of your client's hardware and never make the mistake of designing and testing on the same machine! What is acceptable and what is a basic publication is up to you to decide.

Sorry to bother you Mack, but still can´t get it.
If I have both videos rendered I can´t see them when playing. Only with one on top seems to work.
"To set the layer function", Do you mean to have one video in one Layer and the other one in other layer with the rest of the objects of the page?
I tried that but when I use a button to show or hide the 2nd layer if doesn´t work.
i would appreciate if you can help me on this.

Hi Isma,

I think you might be use the layers palette in the bottom left. This do nothing in published / preview mode.

Simply place the two videos over each other and use the action animation > move to layer.

Select the video that is above the other video and set its layer to -4.

To move it back just set the layer for the same video to 4.
