It is recommended that you test your frame stripping results when compressing animations. While the ACL will strip keyframes that contribute the least error, it may not perform as well for individual sequences when compared to compressing entire animation sets. The error may be lower, but the perceived fidelity loss may be higher than using Unreal Engines default frame stripping techniques. Unreal Engine's frame stripping tagrets a fixed frame rate, which removes keyframes in a uniform manner. While this method does not attempt any preservation of more important key frames, resulting in higher error, the perceived fidelity loss could be lower than the ACL solution.
