Compare hardware and software encoding on a representative sample with the same delivery requirements. A faster export is useful only if its picture, audio and file format still meet the job. Hardware encoding support also does not establish hardware decoding support for the source.

Keep the test conditions visible
| Variable | Record or hold constant |
|---|---|
| Input | Same media and sequence range |
| Timeline | Resolution, frame rate, effects and color handling |
| Output | Codec, profile, dimensions, frame rate and audio |
| Rate control | Target/maximum rate or quality setting, with any differences noted |
| Environment | Editor version, OS, hardware and driver |
| Result | Export time, actual size and observed artifacts separately |
If the two paths expose different controls, document that instead of claiming a perfectly matched encode. Comparing one path’s quality-based mode with another path’s fixed bitrate can answer a practical question, but it is not a pure test of hardware versus software.
Choose a difficult but relevant sample
- Include movement, fine texture, gradients, text and your usual effects.
- Export once with each path using the recorded settings.
- Measure elapsed time with the same start and finish definition.
- Reopen both outputs, inspect them under the same viewing conditions and check audio sync.
- Compare actual sizes. Repeat a suspicious result before generalizing.
Separate the rest of the pipeline
Export time includes more than encoding. The application may have to read and decode source clips, render effects, rescale, mix audio and write the output. If an expensive effect dominates, changing the encoder may have little influence on total time.
Make a delivery decision, not a universal ranking
Use the path that meets the required quality and timing on your system. Record why you chose it. Do not assume that a result from one codec, GPU or application version transfers to another. Recheck the choice after an important driver or application change.
Adobe’s hardware-acceleration documentation describes dependencies for supported encoding and decoding modes; it is not a benchmark for your footage. See three different GPU questions and the sample-based export estimator.
